Yes, in many cases there are "better" chamberings for many people.
For myself, I am one of those individuals who are very recoil tollerent. I shoot most bigger guns just as well as I do smaller rifles, but for many shooters this isn't true. For most, the recoil limit is somewhere near .30-06 level before shooting is negatively effected.
The .300 Wby is just past that limit and for those people a 7mm Magnum or .30-06 might be a better choice.
For those, like myself, who aren't as sensitive to recoil the .338 Magnum is a better choice as it hits a bit harder and (in my experience) kills quicker than the .300's.
What the various .300's have going for them is that they are a near perfect compromise chambering. It's recoil is stiff, but not as punishing as the bigger .338's. It shoots as flat as the smaller 7mm and .270 rifles. And it handles heavier bullets than the smaller chamberings as well....providing better killing power.
It is a near perfect "tweener" round that sits between "too small" and "too big" competitors for most people.
